Hi. How do I bind the result of a non-observable function to a property? as I understand it, I'd need a ChangeListener for that?

Hello I wrote an app that by clicking on different buttons it trigger different command lines ( OS process) I would like to print the output of the commands in a UI component, anyone is familiar with something similar I can take inspiration from ?

Hi Is webView builder working ? I am using the latest version and get error when running the app (beside been red in the IDEA) if yes I will really appreciate some references ? TNX

Hi, i'm new to tornadofx and javafx in general, how can i put data inside this tableview without having to create a custom object the data i want to put inside is a Double.

Hi there, is it possible to make a one row tableview ? and disable selection & hover effects and also remove the scroll panes ? EDIT: Sorry i meant scroll BAR

Hi, I'm total newbie, sorry if the question may sound dumb, but I'm extending

View

and I'm assigning

root

to a

Slider

. How may I create a loop among the slider entries?

Hi. Can help me.

class GFieldSetModel(val Name: String = "")
class MainView : View("Hello TornadoFX") {
    val controller: GFieldSetController by inject()

    override val root = vbox {
        children.bind(controller.fields3) {
            hbox {
                children.bind(it) {
                    label(it.Name) 
                }
            }
        }
    }
}

class GFieldSetController : Controller() {
    val fields1 = FXCollections.observableArrayList( GFieldSetModel("1.1 "),  GFieldSetModel("1.2"))
    val fields2 = FXCollections.observableArrayList( GFieldSetModel("2.1 "),  GFieldSetModel("2.2"))
    val fields3 =  FXCollections.observableArrayList(fields2,fields1 )
    fields3.add(fields1) // it doesn't work
}

Hello everybody! I need some help with something and I hope someone is willing to. So the past month I've been busy creating a very simple app for a client of mine. It is essentially a simple GUI for them to fill a database with questions and answers and stuff that will be used in a mobile app. Now, this is the first time I used TornadoFX for such a job. It looked very simple and I got the job done pretty nicely. There is a problem tho: I finished the application, but I can't seem to export it in any sort of way. That being a .jar or an installer or anything. I'm using IntelliJ for this and I've tried a few methods, like just building artifacts and creating an installer using The Badass JLink/Runtime Plugin, but none seem to work. I am basically desperate for help at this point, because if this doesn't work I will have to make it from scratch again in something like JavaFX, which I sincerely do not want to do. I hope someone is willing to help me. I'm new to this Slack but I hope you can message me or respond to this. With kind regards, Sergen

obviously TableView, not ListView (don't know what I was thinking at 3am)

In a project i'm currently working on I have a custom wizard with multiple pages (views). For every page I have a controller which handles the business logic. Every page requires some data to be filled in by the user. What would be the best way to temporarily save all of this data until the wizard is completed.

given a

Text

node, is there a way to go from mouse click in the node to nearest character in the text?

Don't tell me what I'm doing wrong

private val map = mapOf("1" to "one", "3" to "three", "9" to "nine")
    private val observableMap: ObservableMap<String, String> = FXCollections.observableMap(map)
    override val root = hbox {
        textfield() {
            bind(Bindings.valueAt(observableMap, "1"))
        }
    }

textfield - is not edited.

Hi guys! I can't get TornadoFX to work with Java 16 and Gradle. Is that even possible?

I am having trouble loading a particular Font in my app. The .ttf file is in the resources folder and the path to the file is also correct. This is the code I used to check:

val fontStr = "fonts/FiraCode-Regular.ttf".apply {
  val inputStream = MethodHandles.lookup().lookupClass().getResourceAsStream(this)
  val clazzPackage = MethodHandles.lookup().lookupClass().packageName

  println("FONT LOADING: $clazzPackage -> $inputStream -> ${loadFont("fonts/FiraCode-Regular.ttf", 14)}")
}

The output when I run the application is

FONT LOADING: me.blocky.logreader.style -> <http://java.io|java.io>.BufferedInputStream@6ebd22fa -> null

Clearly, the file is there since the inputStream is not null. But the loadFont method still returns null. Does anybody know what's going on?

Hi, I am creating simple form like this, but I can't find how to create an input to upload a file. Could you point me to some example? Thanks.

I also tried the onKeyPressed field, tho it doesn't take a lambda assignment, with a separate Handler class.

There are a lot of people in this channel - maybe with enough collective experience we can overcome the documentation challenges in Tornado we just have to revive the community

I would love to see that. Desktop work is still real work, and TornadoFx is a huge timesaver. There are some PR's I might make, but the core is first-rate.

May be overtaken by Compose for Desktop one day, but idk how mature that effort is. In the meantime this is about as close as you can get I feel

@Ryan Smith If you or someone else wants to do that, it'd be brilliant. Or maybe take some of the ideas and code from Tornado and make a smaller more maintainable library?

We're doing our bit for the desktop by working on packaging. We just recently launched a new packaging tool called Conveyor that has built in support for JavaFX (and Compose Desktop) apps. Check it out: https://hydraulic.software/

It handles packaging, signing and software update for you, for all three major platforms (well, rpm support is in the works, on linux you get debs and tarballs).

With this a major barrier to making and shipping JavaFX/TornadoFX apps falls away and it becomes way more practical to use them for smaller projects where you still need software update.

I would like to build a JavaFX to build a UI for an existing Kotlin project. I would love to use TornadoFX but I am a bit nervous as TornadoFX has still uses Java 8 runtime and not had an update for a while. The rest of my project (25,000+ lines) has been using the current Java runtime releases and is in production. At the moment I am leaning towards using JavaFX directly. Before I give up, is there a way to use TornadoFX with later versions? Thanks for your help!

On a related note, what's the general state of TornadoFX? It does not seem to be actively developed anymore, but neither does https://github.com/edvin/tornadofx2 seem to gain traction. Which leaves anyone who wants to develop a desktop app with Kotlin in the bad situation that JavaFX with Kotlin is cumbersome if you want to use a DSL, and on the other hand Compose for Desktop is not really mature yet.

I moved to Compose for Desktop. It was unreal. I've since moved onto webapp using three.js because the CfD 3D stuff was too limited.

I am sticking with TornadoFx for now. It does appear to be moribund, but it just doesn't feel like there's anywhere to jump. I'll tell you one thing, my views are heavily isolated from my models which are heavily isolated from my domain code. 🙂

I also moved to Compose for Desktop. There are a few things that I found I had to put together myself e.g. a Table view, but overall I found it easier to get moving quickly with Compose for Desktop than I did with Tornado.

i still use javafx + kotlin, but i copy the dsl stuff from tornado into my project. I have kicked around the idea of splitting just the dsl into a separate library, but never had had the time to work on it. i dont like the dependency injection and other stuff from tornado as much

but i like java 17, so i cant just use tornadofx out of the box anymore
